HYDROGEN BUSES

It's not just a project. Tomorrow will be operational in London, a bus that runs on hydrogen in the tourist route: Covent Garden, Tower of London-South Bank. Triumph of environmentalists and high human spirits in constant struggle to breathe better air quality and have clean cities. If the buses work well and the cost s lower (they are more expensive than existing diesel-powered), the system could be expanded across England and Europe. The buses contain batteries that store electricity generated by hydrogen fuel cells that combine H and O to produce water added to the energy generated during braking process. These buses emit water vapor for 18 hours without refueling, visible in the posterior superior zone of buses. To Madrid, which since 2003 has a small set of hydrogen-powered buses will soon follow Hamburg, Berlin, Amsterdam and other European cities. USA, not far behind will soon open her Hydrogen Highway in California with 30 refueling stations.
